Description
Technical field
The utility model relates to chemical fields, and in particular to orthophosphoric acid dehydration handles special heating furnace.
Background technique
Phosphoric acid or orthophosphoric acid, chemical formula H3PO4, molecular weight 97.994 is a kind of common inorganic acid, is middle strong acid.By
Phosphorus pentoxide, which is dissolved in hot water, can be obtained.Orthophosphoric acid industrially uses sulfuric acid treatment apatite to obtain the final product.Phosphoric acid holds in air
Easily deliquesce.Heating meeting dehydration obtains pyrophosphoric acid, and further dehydration obtains metaphosphoric acid.Phosphoric acid is mainly used for pharmacy, food, fertilizer
Equal industry, including as antirust agent, food additives, dentistry and orthopaedic srugery, EDIC corrosive agent, electrolyte, scaling powder, dispersion
Agent, industrial corrosion agent, the raw material and component household cleaning product of fertilizer.It also is used as chemical reagent, phosphate is all life
The nutrition of form.Studying the earliest chemist of phosphoric acid is french chemist Antoine Lavoisier.1772, he did such experiment: by phosphorus
It is placed on to make its burning in the bell jar of mercury sealing.Experimental result and reach a conclusion that a certain amount of phosphorus can burn Mr. Yu appearance
In the air of amount；Phosphorus generates the white powder piece of anhydrous phosphorus when burning, as thin snow；The about surplus original appearance of air after burning in bottle
The 80% of amount；2.5 times are nearly weighed before relatively burning after phosphorus burning；White powder piece be dissolved in water phosphoric acid.Antoine Lavoisier also confirms that phosphoric acid can
It is made with concentrated nitric acid and phosphorus reaction.More than 100 years have about been spent, German chemist Li Bixi has done the experiment of many agriculture chemistry,
Phosphorus and phosphoric acid are opened to the value of plant life." organic chemistry is in agricultural and physiological effect " written by Li Bixi in 1840
In, the fertility problem of soil is scientifically demonstrated, and point out effect of the phosphorus to plant.Meanwhile he has also further probed into phosphoric acid
And application of the phosphate as fertilizer, enter the large-scale epoch from the production of this phosphoric acid.The production process of phosphoric acid is always by original
The regional impact of material, the production of China's phosphoric acid are concentrated mainly on Yunnan, Sichuan, acid solution and are easy during the dehydration process according to glutinous
Property layering, form that bottom is very viscous and Guizhou, Hubei are flowed in top, in the secondary operation of phosphoric acid, thermal dehydration is system
Standby one of pyrophosphoric acid, the main method of metaphosphoric acid, however phosphoric acid dehydration device in the prior art, mostly with traditional smelting furnace
For prototype, then add additional diversing flow system.Phosphorus is in relatively steady state, and which results in bottoms in phosphoric acid dehydration
Viscous phosphoric acid can the preferable phosphoric acid of mobility to top generate stronger interference, influence the dehydration efficiency of top phosphoric acid.
Utility model content
The purpose of this utility model is to provide orthophosphoric acid dehydrations to handle special heating furnace, to solve phosphoric acid in the prior art

Axis, the axis collinear of the first rotating shaft, the second shaft, and the angle of first rotating shaft, the axis of the second shaft and horizontal plane is
10~15 °, the first rotating shaft is pierced by burner hearth sidewall and is connected with rotating mechanism, and the rotating mechanism is for driving first rotating shaft
Along own axis, the burner hearth inner sidewall also fixed bearing block installs second bearing on bearing block, second shaft with
The second bearing is connected；Expects pipe is arranged close to one end of the second shaft in the furnace body, and valve is arranged in the expects pipe；The furnace
The side bottom of thorax also sets up thorax door, and the thorax door and the bearing seat are on the ipsilateral side wall of burner hearth.
For mobility in phosphoric acid dehydration in the prior art is uneven, there are laminations, the phosphoric acid of bottom can be to upper
The phosphoric acid in portion leads to the problem of strong interference, and the utility model proposes orthophosphoric acid dehydrations to handle special heating furnace, and rotating mechanism is used
In driving first rotating shaft rotation, first rotating shaft drives the furnace body in burner hearth to be rotated, while the second shaft is rotated therewith,
Second shaft keeps stablizing under the action of bearing block and second bearing, thus by first rotating shaft, the second shaft simultaneously to furnace
Body is carried, it is ensured that furnace body being capable of smooth rotation.The angle of first rotating shaft, the axis of the second shaft and horizontal plane is 10~
15 °, therefore furnace body can also be rotated along the axis horizontal by 10~15 °.Expects pipe passes through valve for feeding and discharging
Door control its shutdown, thorax door be in the prior art arbitrarily can with the door of opening and closing, metallic door preferably resistant to high temperature,
For feeding.It in the utility model specific work process, is heated in burner hearth, is turned by rotating mechanism driving furnace body
It is dynamic, furnace body along and horizontal plane angle be 10~15 ° axis rotated so that the liquid phosphoric acid of furnace interior is by whipping,
Under the influence of centrifugal force, liquid constantly carry out whipping with mix so that the phosphoric acid of poor fluidity and good fluidity
Phosphoric acid can always in the mixed process, entire thermal dehydration process remain at phosphoric acid solution more uniformly in the state of
It carries out, to solve in phosphoric acid dehydration in the prior art, layering is serious, upper flow is good, lower flow is poor, on
Phosphoric acid dehydration efficiency low problem in portion's realizes and lower part phosphoric acid is avoided to generate interference to top phosphoric acid, improves phosphoric acid dehydration effect
The purpose of rate.In the utility model, the angle of first rotating shaft, the axis of the second shaft and horizontal plane is 10~15 ° and needs strictly
Control, angle is too small, is difficult to for product being quickly discharged by expects pipe after the completion of dehydration, and angle is excessive, and centrifugal force is dry by gravity
It disturbs greatly, whipping mixed effect is poor, and the effect for causing the utility model to improve efficiency is unobvious.
Several jacks are arranged in the roof of the furnace, and several protrusions, the protrusion and the jack is arranged in the bell bottom
Match, lifting lug is set at the top of the bell.It is carried out detachably between burner hearth and bell by the jack and protrusion that are mutually matched
Connection.Lifting lug is for slinging bell.
The burner hearth lateral wall fixed mounting plate, the mounting plate is for installing rotating mechanism.Mounting plate is rotating mechanism
Installation station is provided, while carrying out carrying and stress.
The rotating mechanism is stepper motor.
The position that the first rotating shaft passes through burner hearth sidewall is arranged first bearing, is fixed on furnace on the outside of the first bearing
In thorax side wall.The stability in first rotating shaft rotation process is improved by first bearing.
The utility model compared with prior art, has the following advantages and benefits:
The utility model orthophosphoric acid dehydration handles special heating furnace, and entire thermal dehydration process remains at phosphoric acid solution
More uniformly in the state of carry out, thus solve be layered in phosphoric acid dehydration in the prior art serious, upper flow is good,
